Web-based digital currency bitcoin hit its highest levels in almost three years on Friday, extending gains since India sparked a cash shortage by removing high-denomination bank notes from circulation a month ago.
Bitcoin was trading as high as $774 on the New York-based itBit exchange, up almost 1 percent on the day and the highest since February 2014, having climbed almost 9 percent in the past month.
Bitcoin is a cash alternative that can be used for moving money across the globe quickly and anonymously with no need for a central authority to process transactions. It has climbed around 80 percent so far this year, far exceeding its 35 percent rise in 2015.
